C# futures: defer
-
Best known for its use in Go and Swift, C# proposal #1398 seeks to add defer statements. If you are not familiar with the concept, it can be summarized as a finally block appearing at the beginning of some code instead of the end.
I could leave this feature for later

It's not at the top of my list.

static void Main() {
Console.WriteLine("Hello"); //1
defer {
Console.WriteLine("Foo"); //5
}
defer {
Console.WriteLine("Bar"); //4
}
defer {
Console.WriteLine("Baz"); //3
}
Console.WriteLine("World"); //2
}Gives: Hello World Baz Bar Foo (Obviously) I can only say: Wow! Just wow! No, hang on, I meant: Why!? Just why!? We seem to have gone from spectacularly minor gains to complete insanity. Please stop fixing a language that wasn't previously broken!

Looks like a goto in a fancy dress.
